macOS 28 will no longer support encrypted Mac OS Extended volumes
Key points
- macOS 28 drops support for encrypted Mac OS Extended volumes
- Users must decrypt or reformat affected storage
- Shift towards APFS file system is evident
Change Announcement
Apple has confirmed that starting with macOS 28, the Mac OS Extended file system will only support unencrypted volumes. Encrypted volumes will become incompatible, necessitating user action to continue using them.
User Impact
Users currently utilizing encrypted HFS+ external drives or legacy Mac-formatted volumes must either decrypt these volumes or reformat them to a compatible file system such as APFS. Apple provides guidance on how users can check their volume's compatibility.
Future Compatibility Notices
Beginning with macOS 26, users will receive notifications when using encrypted Mac OS Extended disks that will not work with macOS 28 or later. The notification will specify the volume name affected.
Instructions for Users
To address the compatibility issues, Apple advises users to back up their data. They can then either reformat the volume to APFS or decrypt the volume if they choose to keep it. Instructions to verify encryption status using Disk Utility are provided.
